OVERCOMING GRAVITY - PLASTIC BOTTLE

OBJECTIVE:
Design an aerodynamic object that will move in the wind.

BACKGROUND:

This activity will have the students design an aerodynamic plastic soda bottle.  Show them an example of what an example of an end product will be like.  The key points for students to acknowledge, is that wind has to be "captured" and made to work.  For example a pin wheel or wind mill. 

There are many designs that students can make.  They can decorate them if they like.  Each student can make one if they bring their own bottle. 

PROCEDURE:
Materials - exacto knife, plastic bottle, fish string, ornaments

First design how you think an aerodynamic plastic bottle will look like.  Remember you plastic flaps to "capture" wind, so the bottle can move around.  After your teacher "approves" your design, then make the design.  In your conclusions state whether the bottle was an aerodynamic success.                 

PROBLEM:  How can a plastic bottle capture the wind?
